polarization makes the charge-distribution in the molecular orbital of H2 molecule to change, thus improving the van der Waals forces between adsorbent and adsorbate. charge-dense species, like metal cations, polarice the H2 molecule and increase the affinity to this molecule.
can u tell me the relation between the adsorption and polarisablity with the increase in number of hydrogens
simply as we move down the column the polarisablity increases
1h2 = 85 ( polarisablity)
.2h2 = 87
.3.h2 =89
4..h2 =92
5 h2 = 94
the hydrogen molecules are the ones that r stored on the complex which i am working on, so what do u think about the effect of increase in polarisablity on hydrogen adsorption ie hydrogens r adsorbed in the molecular form.
